investigation
Film Rt. Wrist AP, Lat :
Distal end radius fracture
Distal end radius fracture
• Most common orthopaedic injury with a
bimodal distribution
– younger patients - high energy
– older patients - low energy / falls
• Falling On an Out-Stretched Hand (sometimes
abbreviated as FOOSH)
• 50% intra-articular
Distal end radius fracture
• Associated injuries
– DRUJ injuries
– radial styloid fx - indication of higher energy
• Osteoporosis
– high incidence of distal radius fractures in women
>50
– distal radius fractures are a predictor of
subsequent fractures
• DEXA scan is recommended in woman with a distal
radius fracture
Classification
• Fernandez: based on mechanism of injury
• Frykman: based on joint involvement
(radiocarpal and/or radioulnar) +/- ulnar
styloid fx
• Melone: divides intra-articular fxs into 4 types
based on displacement
• AO: comprehensive but cumbersome
Fernandez Classification
1. Bending fractures of the
metaphysis
•Transverse fracture at metaphysis
•Extra-articular fracture
•Colles and Smith fractures
2. Shearing Fracture of the joint
surface
•intra-articular fracture
•Barton's fracture, reversed Barton's
fracture
Fernandez Classification
3. Compression Fracture of the
joint surface
•impaction metaphyseal bone (die-
punch)
• intraarticular comminuted fracture
4. Avulsion Fracture of ligament
attachments
•Avulsion of ulnar and radial styloid
process
• radiocarpal fracture-dislocation.
Fernandez Classification
5. Combination of types
•High energy injuries.
Common distal end radius fracture
Colles’ fracture
• Very common extra-articular
fractures of the distal radius
• most frequently seen in elderly
women.
• Fall in to wrist dorsiflxtion
• Dinner fork deformity
• Transverse fracture at distal radial
metaphysis
• Dorsal displacement of the distal
fragment
Common distal end radius fracture
Smith's fracture
(reverse Colles)
• Fall in to wrist
palmarflexion
• volar displacement of
the distal fragment
Common distal end radius fracture
Barton's fracture
• intra-articular fracture
• Shearing force
• Volar type/Dorsal type
• usually associated
subluxation/dislocation of
the carpal bone.
Common distal end radius fracture
Barton's fracture
• intra-articular fracture
• Shearing force
• Volar type/Dorsal type
• usually associated
subluxation/dislocation of
the carpal bone.
Common distal end radius fracture
Die-punch fracture
• a depression fracture of
the lunate fossa of the
distal radius.
• High energy compression
force
Imaging
• Radiographs
X-ray parameters normal Acceptable
Radial height 12 mm <2 mm shortening
Radial inclination 23° change <5°
Ulnar variance 0-2 mm No ulnar pus(ulnar
higher than radius)
Lateral tilt Volar tilt 11° Neutral tilt(no dorsal tilt)
Joint stepping
(intra-articular fracture)
No stepping <2 mm stepoff
Treatment
• High demand hand : physiologically young or
active
Aim  fracture healed with perfect reduction
Decrease long term complication e.g.
post-traumatic arthritis, late midcarpal instability
• low demand hand
Aim  fracture external alignment
Unnecessary to perfect reduction
Treatment-High demand hand
Conservative treatment
• Fernandez type 1 without cortical
comminution Acceptable alignment after
close reduction
= short arm cast 6 weeks  wrist splint 3 weeks
+ROM exercise
Treatment-High demand hand
Surgical treatment :ORIF
Close reduction of
Colles’ fracture
• Pain control
-morphine
-hematoma block
• Traction
• Reverse mechanism
Colles’ fracture  hyperextension of wrist
Reverse mechanism : volar flexion
• Final adjust alignment
Traction-counter traction
Treatment-low demand hand
Conservative treatment
= immobilize without close reduction
By short arm cast 6 weeks  wrist splint 3
weeks +ROM exercise
In severe external malalignment  close
reduction
*Osteoporosis treatment
complication
1. Compartment syndrome
2. Median nerve neuropathy
3. Distal radio-ulnar joint instability
4. Post- traumatic arthritis
5. malunion
Male 41 year,
motorcycle accident
Falling On an Out-Stretched Hand
investigation
Film Rt. Wrist AP, Lat :
Diagnosis
• Volar Barton's fracture
Plan of treatment
• Close reduction and short arm AP slab for
immobilize
• Set OR for ORIF with P&S
Film Rt. Wrist AP, Lat
post close reduction
